Matlab shutdown Deterministic solution, stack_solve_algo=1

Perfect foresight simulations
1

Dear colleagues,

I am writing because there seems to be a problem somewhere between dynare matlab when I use stack_solve_algo=1, maxit=80. Specifically, matlab shuts down whenenver I run a specific set of codes with this option. It does not shut down when I use say option stack_solve_algo=2, or 3. Here is some more information:

  • Dynare version: I tried version 4.5.6, 4.5.1 and 4.4.3
    -Matlab version: see past below
    -Error message: sometimes matlab produces an error message before shutting down, which I have attached.

Many thanks for your help!

Best,
Ansgar

Hi Ansgar, this is a bug in the bytecode-mex-file. Could you please provide us and in particular @sebastien with the mod-file for debugging purposes.

Hi Johannes,
thanks for your quick response, here are the .mod files. You need to run dynare surprise_solution_2019_05_20. I hope it won’t be to cumbersome, I couldn’t reproduce the problem in a simpler code… surprise_solution_2019_05_20.zip (1.6 MB)

Best,

For the moment I seem to have found a workaround though, so please don’t waste your weekend on this…

@sebastien The file also crashes 4.5.7. On the unstable, after fixing nameindices.mod (1.9 KB)
I get the error

Invalid MEX-file

This seems to be an issue related to compiling on Windows that needs to be fixed first.

I can reproduce the crash on both unstable and 4.5.

Since I am not familiar with the bytecode stuff, I have opened an issue and assigned it to Ferhat.

Regarding the missing dependent shared library error that you get under Windows, I can’t debug it right now (don’t have access to my Windows VM). Do you confirm that it still occurs with the latest snapshot?

Yes. I used the May 22, 2019 version (446a413). The only commit since has been your change in the Dynare++ comments.
